20100252249 | DEVICE FOR IN SITU EXTRACTION OF A SUBSTANCE COMPRISING HYDROCARBONS - A device for in situ extraction of a substance including hydrocarbons while reducing the viscosity thereof from an underground storage site is provided. The device includes at least one production pipeline leading out of the storage site, and at least two electrodes which are inductively and resistively effective relative to at least parts of the storage site. | 10-07-2010 |
20110042063 | Apparatus for in-situ extraction of bitumen or very heavy oil - An apparatus for the in situ extraction of bitumen or very heavy oil from oil sand deposits, and applying heat energy to the deposit to reduce the viscosity of the bitumen is provided. A high-frequency generator feeds electric power to a linearly extended conductor loop at a predefined depth of an oil sand deposit, the inductance of the conductor loop is compensated in some sections or continuously. Advantageously, one of the conductors of the conductor loop may be disposed substantially in a vertical direction above the extraction pipe. | 02-24-2011 |
20110227349 | METHOD FOR EXTRACTING BITUMEN AND/OR ULTRA-HEAVY OIL FROM AN UNDERGROUND DEPOSIT, ASSOCIATED INSTALLATION AND OPERATING METHOD FOR SAID INSTALLATION - A method for extracting bitumen and/or extra-heavy oil from an underground deposit is provided. The energy for producing the steam and for the electric heating is generated in situ, for which purpose part of the extracted bitumen and/or extra-heavy oil is burned in an industrial turbine with a downstream generator coupled to the turbine. The industrial turbine may be a gas turbine or a steam turbine. In particular the industrial turbine with downstream generator is assigned a waste heat recovery steam generator which serves for generating the steam and accordingly takes the form of a boiler. Through intermediate storage of the bitumen and/or ultra-heavy oil produced it is possible to implement a self-contained closed circuit which operates autonomously, independently of any external energy supply, using approx. 20% of the extracted bitumen and/or extra-heavy oil for the purposes of extraction. | 09-22-2011 |
20130062064 | METHOD AND DEVICE FOR THE "IN-SITU" TRANSPORT OF BITUMEN OR EXTRA-HEAVY OIL - A technique is provided for extracting a substance containing hydrocarbon from a reservoir, wherein the reservoir is applied with thermal energy in order to reduce the viscosity of the substance. As per the technique, at least two conductor loops for the inductive energization are provided as electric/electromagnetic heating elements. Each of the at least two conductor loops has at least two extended conductors, which are guided horizontally inside the reservoir. At least two alternating current generators are provided for electric power, each being connected to a respective conductor loop. The technique involves operating a first of the at least two alternating current generators and at least a second of the at least two alternating current generators synchronously with respect to their frequency and with a fixed phase position in relation to one another. | 03-14-2013 |
20130192831 | DEVICE AND METHOD FOR THE RECOVERY, IN PARTICULAR IN-SITU RECOVERY, OF A CARBONACEOUS SUBSTANCE FROM SUBTERRANEAN FORMATIONS - A device is provided for extracting a hydrocarbon-containing substance from a reservoir. Thermal energy can be applied to the reservoir in order to reduce the viscosity of the substance. The device includes at least one conductor loop for inductively supplying electric current, to provide electric and/or electromagnetic heating, and a fluid conducting device for transporting and introducing a solvent fluid into the reservoir, to further reduce the viscosity of the substance. | 08-01-2013 |
20140178208 | SYSTEM FOR GATHERING GAS FROM A GAS FIELD COMPRISING A HIGH EFFICIENT HIGH PRESSURE COMPRESSOR - A system includes a high pressure compressor having a gas input and a gas output. The gas input is coupleable to a gas field for receiving a gathered gas with a first gas pressure, and the gas output is coupleable to a gas export system for providing the gas with a second gas pressure, which is higher than the first gas pressure, to the gas export system. The system also includes a measuring unit coupled to the gas input. The measuring unit measures an input mass flow value indicative of an input mass flow at the gas input. The system also includes a mass flow control unit that is coupled to the measuring unit for receiving the measured input mass flow value and the gas input for controlling the input mass flow such that the measured input mass flow value corresponds to a set point input mass flow value. | 06-26-2014 |
20150308248 | Device and method for obtaining, especially in situ, a carbonaceous substance from an underground deposit - An apparatus is provided for delivering a substance containing hydrocarbons from a reservoir.
